TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 439,544, dated October 28, 1890.

Application filed June 17, 1886. Serial No. 205,391. (No model.)

To aZZ whom it may concern:

Be it known that I, ULYSSES SHERMAN Mo- CORMACK, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Typerio ing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable 0th [0 ers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to let ters of reference marked thereon, which form a part of this specification.

This invention relates more particularly,

though not exclusively, to certain improvements in that class of type-writing machines represented by the one commonly known in the market as a caligraph, the object of the an invention being to facilitate the process of writing on a sheet or page columns of words or figures, and to do so more accurately, whereby the appearance of the page is greatly improved, and in the case of figures greater 2 5 correctness in adding is obtained.

The invention consists in the arrangements and combinations of parts, substantially as will. be hereinafter set forth, and finally embodied in the claims.

0 Referring to the accompanying drawings, in which like letters indicate corresponding parts in each of the several figures, Figure 1, Sheet 1, is a side elevation of a portion of a ealigraph-frame having my improvements thereon. Fig. 2 is a plan of the paper or sheet carrying portion thereof, havin gsecured thereto a slotted stop bar or rack, upon which are arranged certain adjustable stop-pieces which embody important features of the invention; and Fig. 8 is a detail view of a certain stop, hereinafter more particularly re ferred to. Fig. 4., Sheet 2, is a back view of the machine or that portion thereof to which my improvements more particularly relate.

5 Fig. 5 is an enlarged rear elevation of the rack above referred to. Fig. 6 is a sectional View taken through line 00 in the last said figure. Fig. 7 is a detail view showing a modification in the construction of an adjustable stop-piece, and Fig.8 is a front elevation of the lower part of the said piece.

In said drawings, a indicates the frame or bed of the typewriting machine, which may be of any suitable construction to receive the type and mechanism for operating the same, which last parts it is deemed unnecessary to show herein.

I) is the platen supported by the carriage c in any usual manner. To the rear carriage bar 0', depending therefrom over the carriage- 6o shaft (1, is secured a rack e of peculiar construction, being provided with teeth to engage the letter-space dog in the usual manner, and in addition thereto adjustable stops by means of which the columns are formed on the page in the positions desired. The said rack is vertically and longitudinally slotted, as shown at 6, Figs. 2 and 6, and on the under side, back of the ordinary teeth f and 9, said rack is provided with teeth or a notched surface or edge h, which is engaged by a forwardly-extending lug i of the adjustable stoppiece j. Said stop-piecej extends vertically through the slot of the rack, as shown in Fig.

(3, the forwardly-extending lugi engaging the notched under surface of the rack. At the upper side of the rack the stop-piece is provided with a set screw or not A", Fig. 7, or with any other suitable holding device or clamp, the preferred construction being shown in Figs. 5 and 6, in which Z is an eccentric which is pivoted on the stop-piece and bears on the top of the rack or on a plate m arranged thereon. By raising the finger-piece Z of the eccentric the lug is allowed to fall from engagement with the rack-teeth h; but by depressing said finger-piece the said lug will be brought up into holding relation, as in Fig. 6. Vhen the stop is thus clamped and when the dog is released from the usual spacing-teeth of the rack and the carriage is thus allowed to move on the ways of the frame under the influence of the ordinary main actuating-spring o, the concussion caused by the engagement of the holding-dog n with the said stop-piece will not displace the latter and produce an irregularity in the vertical alignment of the column of words or figures, as will be understood.

The rear face of the rack is provided with graduation-marks 0 0, Fig. 5, which are num-. bered to tally with those of the ordinary carriage-scale 19, Fig. 1, at the front of the machine, the stop-pieces or the plates on moving therewith being provided with pointers or indeX-fingers q, to allow an exact adjustment of the said stops.

The dog a, the dog-holder s, and rocking bar it are of the usual construction and arrangement, and are operated by the universal bar u in the usual manner, the dog at being thrown by said universal bar from the teeth f of the sliding portion of the rack to the teeth g of the body portion thereof when the key and the said bar to are depressed. To throw the dog a forward beyond the teeth f 9, so that the carriage with the column-stops therein will move under the influence of the main spring 1) until its-motion is obstructed by the said stops j, I have provided a lever or arm w, which is attached to the rocking bar If at a point near, its pivotal bearings at the side of the machine, and extends upward and forward at one side of the group of connecting bars or rods (not shown) for operating the type hammers or levers to the fore part of the machine, where it is provided with a finger portion or piece w. The spring action and the adjustment of this said lever or arm w causes it to normally hugthe inner'surface of the portion 10 Fig. 1, of the frame, which is provided with a stop piece or portion wiwhich projects beyond the said inner line and serves to hold said arm win place while the machine is in ordinary use. The forward movement of the dog a, under the influence of the depressed arm 10, is .limited by that portion of the rack marked h, Fig. 6, which hangs down slightly below the line of the teeth f g.

In operating the device the column-stops are first arranged in or on the rack e in a series corresponding with the line of first letters or numbers of the desired columns. The carriage is then brought to aposition to begin the line of written matter, and the said line is commenced by operating the keys in the usual manner. Then the first column is finished and it is desired to begin the second column, I press upon the lever w,which throws the dog off of the rack 6 into a slot or space behind said rack as will be understood upon reference to Fig. 1, which allows the carriage to move forward until it comes to the stop, as will be understood upon reference to Figs. 1 and 6,when the spring which actuates the dog will throw the latter back into engagement with the rack e, preparatory to repeating the operation.

The chief advantage in this improvement is that when it is desired to make a break in a line or lines of printing, as in making out a bill, and leave a space of some length between the items and the figures at the end of the lines it can be done by setting the stops on the rack e to the figures corresponding with the carriage-scale where it is desired. Then by simply pressing once upon the lever 10, when it is desired to make the break in the lines and move to the figure'column, the carriage will at once move forward until the dog meets the stop. This secures automatically absolute uniformity in the vertical line of figures.

In the ordinary machines it is necessary to strike the space-bar thirty times (more or less) to secure the desired length of break, and thus in the improvement considerable time is saved and the machine is less noisy.

There may be as many breaks in a line as there are stops on the machine. Usually I employ six or eight.

I do not claim, broadly, as myinvent-ion the combination,with the carriage, of adjustable column-stops, a dog to engage the same, and a finger piece or key to actuate said dog, nor the combination,with a dog and slotted rack, of a series of stops adj ustably arranged on said racks. Neither do I claim the combination of the driving mechanism, the rocking frame carrying the pawl, the carriage provided with three racks, one of them having a less number of teeth than the others, andmeans for vibrating the rocking frame and throwing the pawl farther forward to co-operate with the rack having the less number of teeth.

Having thus described the invention, what I claim as new is- 1. In a type-writing machine, the combination of the dog n and means for operating the same, and rack having teeth f, g, and h, of an adjustable column-stop, said parts being arranged and adapted to operate substantially as and for the purposes set forth.

2. In a type-writing machine, the combination,with the slotted rack having the teeth f, g, and h, a dog a, and means for operating the same, of an adjustable stop j, held in the slot of said raclgsubstantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 7th day of June, 1886.

U. SHERMAN MCOORMACK.
